In order to understand the application standard of finned tube radiator, the whole process of heat conduction and its definition must be mastered when carrying out the actual operation. The heat conduction of all the machines and equipment refers to the whole process of heat transfer from the heat flux to the cold flux through the solid partition wall, and also includes the whole process of heat transfer of the wall thickness. The key to the whole process of heat conduction and the size of heat transfer is the characteristics of convective heat transfer on both sides of the partition.
The larger the temperature difference needed to transfer the heat of the enterprise, the larger the heat transfer coefficient will be. The heat transfer coefficient is equivalent to the heat transfer index. Finally, it shows that the larger the heat transfer index is, the smaller the heat transfer coefficient will be. On the contrary, the smaller the heat transfer index is, the larger the heat transfer coefficient will be. The heat transfer index of the gas side is lower than that of the water side, so the heat transfer coefficient of the gas side is higher than that of the water side, which becomes the key heat transfer coefficient endangering the heat conduction and makes the gas side become a short plate in the whole process of heat conduction without heat transfer.
In order to reduce the heat transfer coefficient on the gas side and get rid of the bottleneck effect on the gas side, a variety of countermeasures will be adopted in the design of the heat exchanger, i.e. the fin tube radiator will be used to lift the plate fin type on the outer surface of the gas side. The finned tube radiator expands the original total heat transfer area on the gas side and fills in the characteristic of low heat transfer index on the gas side.
The main use of laser welded finned tube radiator is expanding continuously, and the types and specifications of its products are increasing day by day. In order to facilitate the design and manufacturing of finned tube radiator heat exchanger, the finned tube radiator must be classified, From the fusion of main use and structure, finned tube radiators can be classified into four categories: finned tube radiators for heat transfer with gas, finned tube radiators for heat transfer with smoke, finned tube radiators for heat transfer with substances and cooling substances, and finned tube radiators for heat removal of electrical components.
During the operation of laser welded finned tube radiator and gas heat transfer finned tube radiator, according to its processing technology, it can be divided into wear-resistant steel tube composite cold-rolled finned tube radiator, overall cold-rolled aluminum finned tube radiator, stainless steel plate metal laser welding machine finned tube radiator, spiral wound finned tube radiator, L-shaped finned tube radiator, Flat fin tube radiator.
